| Abstract: | According to the forming mechanism of soil gases above faults,the abnormal geochemical features of mercury and radon on Maqu active fault are analyzed.The position,occurrence and mechanical property of Maqu active fault are determined by the abnormal geochemical features,and which are consistant with the scale and characters of the fault from the fault section.The conclusions provided a useful reference for active faults evalution. |
